FRONT-AIME CON STBUCTION.

Applioation med June l, 1917.

To all whom it may concern IBe it known that I, EDWIN R. EVANS, u citizen of the United States of America, sidin et Detroit, in theeounty of Wayne and tate of Michi an, have invented certain new Jand useful vinpro vement; in Front- Axle Constructions, of which the following is" a. specification, reference. being had there in to the accompanying drawings.

This invention relates to front axle conf struction for tractors and other vehicles, and the primary 'object of my invention is to furnish n novel` iront axle with n Strong' and durable 'front end beatingr for :L traotor freine and. parte thereof, the bearing inc-lud. ing e. leaspring' that obvintee the necessity of using shclxle arme, the lee-i spring hav in a limited action relative to the frontax e, wither?. interfering 4with normal iid-- justments t. the iront end' of the tractor freine relative to the front miie.

A furtherobjeot of my invention is to er tieulete the front end of the tractor `or freine relative to a front axle so that the it'ront axle Vmay assume various inclinations without ein feoting the position of the tractor body or frame. Such en arrangement permits of u tractor traveling over very irre ruler `ground, es eneountereo. in plowed fie d or on extremely rough roede.

The above ere a. fe-vf of the objects no tained bye meohenieal construction vvhioli will be hereinafter epeeiiioelly cleeorilied and then claimed, and referei'ice will now be had to` the drawing, wherein Figure 1 is a front elevation of the axle oonstruetion and .the bea-ring of the traotor frame; h

` Fig` 2 is a pienV 0f the saine with the treo tot :treme removed, and

" Fig, '3 is e central vertical sectional View @of the front axle construction.

4The frontl axle is composed of'two chennel bars 1 -arranged in parallelism, beek to bac-k, as best shown in Fig. 3, and the'ends of! these channel bars are connected, as at 2, with beerlngs 3 `therebetween for the knuckleer of steering wheels (not shown).

Riveted or otherwise connected to the 11p-f er lateral fiallges of the bars 1 edjaeent'the esi-rings 32 are channel bea-rings 4 and 5 having the side flanges thereof connected by pins 6A and .7 respectively.

Connected to the pin 6 of the bearing 4 in the usual and vvell known manner is an end of a leaf spring 8 disposed longitudi Speoication ot Letters Patent.

nelly of the :front axle with the opposite end thereof extending under the pin. I und resting upon the bearing 5. With only one end of the spring 8 fixed relative to the front enfile :Seid Spring muy yield sind nerve de at cushion member, without using shackle urine :it the ends of said epi-ing.

lhnbraoing the 'opper portion of the Spring 8, intermediate the eniif: their il", e fiile-rum member il and this naomi-ber is held on the intmmeciiete portion oi' the spring F5 by straps l() and scri-iw ooit-s il. The ful-- oruifn. member 9 has a, longit linal opening l2 to reive u, pivot bolt 1.3, 'ea-id bolt tending through the 'front onli freine le of e trent-or 151. The fnlornni member 9 also het: e vertical opening ifi in nlinenient with an opening l? centrally of the spring 8, and extending upwardly through the openingo 17 and tapped or otherwiseseoured in the owen ing l@ a. depending T 'bolt 18. The T bolt 18 extends through a stop or guide plete 19 connecting the channel bars l of the front wie, and with the hea-l of said -T bolt between the channel bers l, upward movein' t or fiexure of, the spring 8 isV .limited l the need of the bolt engaging the .stop member i9. Y A' The seine fastening Ineens oonnec-.ting `the' bearings 3 to the front axle may also assist in holding the endg of radius rods. 9.0 at the ends of the front axle, seid radins rods being connected by e connecting member 21.

Frein the oregoingfit wili be observed that the front alti niey lieve tilting notion relative to the tractor freine, Without aecting the stability of the traotor'and'withoutstrain or stresses;

One embodiment of mynveution has' been illustrated but it is to'befae' f dtlittlie: structurel elements are suscepible tof; modifications and variationsA as fall 'with the scope of the appended claims.' 4

VYhat I claim iszi 1. front axle construction and henri* for :atl vehicle frame, ,comprising hennnl bars, arranged in perallelismyaJ leef` spri having one end. thereof heldon Said cheline bars and the opposite end thereof looepn,

. l w The front Iend fremelt Qitheztrtql" fies mediate the ends of said springend adapted to pivotally support a vehicle frame, and means carried by said fulcrum member adapted to limit the fiexure of said spring in one direction relative to said channel bars.

2, The combination of an axle, a lea-f spring on said axle having an end thereof held by said axle andthe other freeon said axle, and means adapted to engage said axle to limit the upward )flexingv of said spring.

A front axle construction and bearing for a tractor' frame, comprising channel. bars, knuckle bearings between the ends of said bars, a leaf spring :havin one 'end thereof fixed adjacent to one of Said knuckle bearings and the other end, thereof looee adjacent the other knuckle bearing, a fulcrum member carried by said spring, and adapted for pivotally holding the 'front end of the tractor frame, and means carried by said ulcruin member extending between said channel bars and adapted to limit the fiex nre of said spring in one direction.

el. The combination with a tractor frame,

of a front axle 'a leaf spring having one endv thereof fixed relative to said axle'andsthe other end thereof loose and adapted to have flexure thereof limited in one direction by said-axle, a fulerum member carrled by said Y spring and pivotally connected to said tractor frame, and means carried by said fulcrum member having -a limited movement relative 'to said axle adapt'edto limit the flexure of Said spring in the oppoite direc' tion.

5. The combination with a tractorrame', of a front axle, channel. bearings 'carried thereby, a leaf springr having one end theren of fixed in one of said bearings and the op? posite end thereof loose in the other bearing, a fulcrum member carried'by said spring and pivotally connected .to said tractor frame, and means connected to Said fulcrmn member and extending through s'aid springand havingr a limited movement' relative 'to said axle adapted to limit the iiexnre of.

said spring in one direction.

6. The combination of a front axle, a

spring thereon, a member intermediate the ends of said spring, a tractor 'frame having the front end thereof pivotally connected to said member, and means carried by said member havingr a limited movement relative to said axle to limit the fiexure of said spring away from said axle.v V l In testimony whereof aix my signature in the presence of two witnesses.
